A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.

During the last two decades it is observed that the increase in electricity demand and environmental concerns resulted in a rapid growth of power production from renewable energy sources. Among all renewable sources, wind energy is one of the most costs effective forms to generate electrical power. In Canada, government initiatives to advance the expansion of wind energy were implemented moderately later than many other countries around the world. However, since 2001, Canadian wind energy has grown to become one of the world's largest and fastest growing markets, driven largely by national production incentives and provincial renewable energy targets. In this book, two case studies are presented based on the eastern part of Canada. The book gives a detail analysis of wind energy based isolated power systems, as well as wind farms for remote grid systems. Review of the existing literature is discussed in the second chapter of this book. In the third chapter, the mathematical models of different components in wind-diesel hybrid power systems are developed.
